New for EditShare at NAB 2013 [b]EditShare V7/b
• This latest release operates on the most performant and capable Linux OS ever
• [b]EditShare Connect/b now sports a totally new and intuitive interface that provides much-requested features, such as “Project Profiles” (the ability to remember what spaces need to be mounted for different projects), a System Status indicator, and translation support for virtually any local language
• A new [b]project sharing plug-in panel for Adobe Premiere CS7/b

[b]EditShare Field 2/b
EditShare Field 2 is the all-new, quiet and portable powerhouse that includes Flow asset management, all in a box small enough to meet airline standards for carry-on luggage. It’s perfect for creating a collaborative, multi-editor environment in a hotel room, on a movie set or in a small news bureau. With the [b]Flow SDI ingest option/b, users can record up to two channels of HD in leading codecs (XDCAM-EX35, DNxHD, DVCProHD, etc). The edit-while-capture capability lets you start editing the moment you begin recording — perfect for ENG applications when you want to be the first to get a story on the air. With an optional lightweight expansion unit, storage can scale up to 24 Terabytes.

New Connectivity Options
[b]10GBaseT /b— economical 10-Gigabit connectivity over standard CAT 6 copper cables — is the latest wave in Ethernet technology. EditShare has multiple switch options including an EditShare-customized version of Arista's ground- breaking 52-port 10-Gigabit switches. A user-friendly interface is designed into the switch with the simple management features you expect from EditShare products.
New [b]Flow 3 with Air Flow and Flow Automation/b
In this new version, Air Flow and Flow Automation join the already popular Flow Browse, Flow Logger and Flow Ingest tools.
Air Flow is the new web browser-based connection to the powerful Flow Asset Management system. It allows users to access Flow over the Internet for remote browsing, tagging and organizing media assets.
Flow Automation provides new indispensable tools for setting up automated tasks such as transcoding and moving files based on easy-to-configure rules.
Other enhancements in Flow 3 include more powerful video editing and trimming; a new customizable user interface that gives users greater flexibility in arranging panes to maximize productivity; and support for non-video clips such as audio files, still images and documents.

[b]Geevs Sports/b
Geevs Sports offers a complete broadcast solution for sports coverage that includes a video server with an integrated Multiviewer and an efficient tactile Controller. It’s a cost-effective, value-added package that is ideal for broadcasters, Outside Broadcast companies (OBs) and In-Stadium television producers. Toolsets for marking key game plays for highlight creation and playback with different angles are quick and easy to use.

[u]Key Features of Geevs Sports:/u
• Four inputs and two outputs
• The agile and compact custom controller gives operators precise access
to playlist functions with a minimum number of keystrokes.
• Integrated Multiviewer displays the different screen sources with clip
names and time codes — all within a single screen.
• Tallies can also be added to sources so operators can easily identify clip
usage elsewhere in the production.
• Add Mark-ins for events in the game. Build highlight lists for playback.
• Smooth, jitter-free replay of highlights and key plays with variable
forward and reverse speeds; stop mode for still-frames.
• With integration between Flow and Geevs Sports, assistants can organize
and edit clip lists in Flow Browse and prepare them for playback.
• Capture directly to central storage, where NLE editors and Flow users
have access to both high-res and proxy files while the recording is in progress.

[b]Geevs Post/b
Geevs Post is a multipurpose ingest server for playout and file delivery in production and post-production environments.
[u]Key Features of Geevs Post:/u
• Standard two inputs and two outputs in a new compact 2RU chassis.
• Scalable by stacking multiple Post servers together for additional video I/O; can be ganged together for simultaneous recording of all channels
from a single client
• Geevs Post has the same powerful wide range of codecs included in Geevs
server products
• The integrated Multiviewer displays sources with clip name and time code
— all within a single screen. A tally can also be added to each source to identify for the operator where sources are being used elsewhere.
• New Scheduler client. A new easy-to-use client to add scheduled calendar events for recording. Add events using the clutter-free interface. It’s easy to set up repeat recordings.
• Integrates with EditShare’s central storage and Flow.

[b]Dense Ark Disc Unit/b
EditShare will also preview the new Dense Ark Disc Unit at NAB 2013. This cost- effective, compact unit stores up to 240 TBs of storage in a 4U space.

[b]Technical Details/b
Break volume into smaller groups called Resource Groups.
- Each file is assigned to a different Resource Group.
- When several files are written, Resource Group assignment reduces the chance of files being allocated to the same group; thereby minimizing fragmentation.

Do Preallocation when a file becomes larger.
- Preallocation reserves blocks in advance which helps keep the file extent to a larger size.
- This technique primarily helps when file size is large. Only a small ratio of blocks will be wasted to minimize fragmentation.

Preserve Reservation Window for active files.
- Preserving the Reservation Window works differently when compared to the Preallocation technique.
- While perserving the Reservation Window, memory blocks are preallocated to prevent other files from allocating the same blocks to help minimize fragmentation.

Allocate by Goal.
- The File System will try to allocate adjacent blocks from layout. Also it will try to lookup adjacent free extents to allocate. This provides better result when trying to find new Reservation window./quote

I've got an A-Class in our lab, and have tested it with Mac and Windows clients, seeing really good speed. I haven't been able to test with video or with a good number of clients yet. I'm hoping to do that in the next few weeks.

Those links shed less light on it than what Aaron has shared. We are technical people here at XSanity, looking for some technical insight into how VTrakFS works, and what it looks like to administrate it in our environments. We read kb articles, not press releases.

The inner workings of our filesystems are important to us in this community. Can you send an engineer to us to shed some light?
